The Second Edition of Hanyu Da Zidian is a large-scale Chinese dictionary that aims to comprehensively and accurately represent the diachronic development of the form, pronunciation, and meaning of Chinese characters. Its compilation not only emphasizes the extensive collection of pronunciations and definitions recorded in historical documents, but also stresses the close integration of form, pronunciation, and meaning, consistently adhering to the core principle of aligning pronunciation with meaning. However, due to the vast number of characters included and the complexity of their sources, certain character entries inevitably exhibit improper matching between phonetic notation and definition. Building on the collation and research of previous scholars, this study systematically consults major historical character and rhyme dictionaries such as Shuo Wen Jie Zi, Guang Yun, and Ji Yun, and examines typical cases of characters with variant readings and polyphonic characters. Through illustrative analysis, this paper identifies specific instances of mismatched pronunciation and meaning in Hanyu Da Zidian and summarizes three main types of causes. First, uncritically following earlier sources without careful examination, directly adopting erroneous pronunciations or definitions from previous character and rhyme dictionaries without re-examining the original texts; Second, conflating distinct senses without careful differentiation, erroneously matching a pronunciation originally belonging to sense A with sense B, thereby disrupting the correspondence between pronunciation and meaning; Third, extensively collecting pronunciations and meanings from texts without verification, relying on secondhand citations of documentary evidence without reviewing the original correspondence between pronunciation and meaning in the primary sources, resulting in unfounded matches. Clarifying these errors and their causes may provide useful reference for the future revision of this dictionary.
